So far as I can tell, nothing. Isaac Newton is arguably the least original thinker in world history. "... we are like dwarfs on the shoulders of giants...." -- Bernard of Chartres "If I have seen further, it is by standing on the shoulders of giants". -- Isaac Newton. Have scientists ever actually read Newton? None so far as I can tell. The Bible warns us about the moderns: "... they will carry their riches upon the shoulders of young asses" -- Isaiah 30:6
